[cfe-dev] How long should a compile of a single C file with a vast number of macros take?

A colleague of mine wrote some test cases in a single huge C file with a
lot of macros.

GCC takes a few seconds to compile the file, but Clang takes apparently
more than 10 minutes - I canceled it at that point.

How can I track down the problem? I guess C-Reduce won't cut it this
time, because it's a performance problem.
